在WCF中,对于webHttpBinding,当服务器使用基本身份验证时,如何在客户端web.config中指定凭据？

我有两个WCF RESTful服务 – “一般”服务是公开的,没有安全性;我打算使用基于SSL的基本身份验证的“admin”服务.这是我的服务器端web.config：

<system.serviceModel>
    <bindings>
        <webhttpBinding>
            <binding name="general" maxReceivedmessageSize="2147483647">
                <readerQuotas maxArrayLength="2147483647" maxStringContentLength="2147483647" />
                <security mode="None">
                    <transport clientCredentialType="None" />
                </security>
            </binding>
            <binding name="admin" maxReceivedmessageSize="2147483647">
                <readerQuotas maxArrayLength="2147483647" maxStringContentLength="2147483647" />
                <security mode="Transport">
                    <transport clientCredentialType="Basic" />
                </security>
            </binding>
        </webhttpBinding>
    </bindings>
    <behaviors>
        <serviceBehaviors>
            <behavior>
                <serviceMetadata httpGetEnabled="true"/>
                <serviceDebug includeExceptionDetailInFaults="false"/>
            </behavior>
        </serviceBehaviors>
        <endpointBehaviors>
            <behavior name="web">
                <webhttp/>
            </behavior>
        </endpointBehaviors>
    </behaviors>
    <services>
        <service name="MyNamespace.Appservices.Generalservice">
            <endpoint address="" binding="webhttpBinding" contract="MyNamespace.Contracts.IGeneralservice" behaviorConfiguration="web" bindingConfiguration="general" />
        </service>
        <service name="MyNamespace.Appservices.Adminservice">
            <endpoint address="" binding="webhttpBinding" contract="MyNamespace.Contracts.IAdminservice" behaviorConfiguration="web" bindingConfiguration="admin" />
        </service>
    </services>
</system.serviceModel>

在客户端,我目前的代码如下：

private static IGeneralservice GetGeneralChAnnel()
{
    WebhttpBinding binding = new WebhttpBinding();
    binding.Security.Mode = WebhttpSecuritymode.None;
    binding.Security.Transport.ClientCredentialType = httpClientCredentialType.None;
    binding.MaxReceivedmessageSize = Int32.MaxValue;
    binding.ReaderQuotas.MaxStringContentLength = Int32.MaxValue;
    binding.ReaderQuotas.MaxArrayLength = Int32.MaxValue;

    WebChAnnelFactory<IGeneralservice> cf = new WebChAnnelFactory<IGeneralservice>(binding,new Uri("http://localhost:1066/Generalservice"));
    IGeneralservice chAnnel = cf.CreateChAnnel();
    return chAnnel;
}

private static IAdminservice GetAdminChAnnel()
{
    WebhttpBinding binding = new WebhttpBinding();
    binding.Security.Mode = WebhttpSecuritymode.Transport;
    binding.Security.Transport.ClientCredentialType = httpClientCredentialType.basic;
    binding.MaxReceivedmessageSize = Int32.MaxValue;
    binding.ReaderQuotas.MaxStringContentLength = Int32.MaxValue;
    binding.ReaderQuotas.MaxArrayLength = Int32.MaxValue;

    WebChAnnelFactory<IAdminservice> cf = new WebChAnnelFactory<IAdminservice>(binding,new Uri("http://localhost:1066/Adminservice"));
    cf.Credentials.username.UserName = "myUserName";
    cf.Credentials.username.password = "mypassword";

    IAdminservice chAnnel = cf.CreateChAnnel();
    return chAnnel;
}

问题是,由于我显然不想硬编码所有这些配置信息,我需要如何在客户端的web.config中提供它？对于我来说,绑定元素在客户端上看起来和服务器上看起来完全相同,这是非常明显的.但是,在哪里可以指定分配给WebChAnnelFactory的凭据？

任何帮助和/或洞察将不胜感激.

谢谢,
